TRIP LATCH STAKE POCKET Beta Vinson, Emporia, Va. I Application May 20, 1952, Serial N0. 288,811

1 Claim.

This invention relates to logging vehicles, and more particularly to remotely controlled release means for the stakes of a logging vehicle to allow the stakes to be released when the vehicle is to be unloaded.

The main object of the invention is to provide a novel and improved stake releasing means for releasing the stakes in a logging vehicle from a remote position, whereby the vehicle may be unloaded without risk of injury to the operator, the improved means being simple in construction, being easy to install, and being reliable in operation.

A further sheet of the invention is to provide improved means for releasably supporting the stakes of a log-carrying vehicle, the means being arranged for simultaneous release of the stakes from a remote location, whereby the logs on a vehicle may be unloaded Without risk of injury to the operator, the improved device involving inexpensive parts, being sturdy in construction, and being substantially positive in operation.

Further objects and advantages of the invention will become apparent from the following description and claim, and from the accompanying drawings, wherein:

Figure l is a fragmentary perspective view of the rear end portions of longitudinal frame members of a log-carrying vehicle equipped with improved stake supporting means according to the present invention, said supporting means being shown in locked position with a pair of stakes supported therein.

Figure 2 is a fragmentary enlarged top plan View of one of the stake-receiving pocket struc- I tures of Figure 1.

Figure 3 is a cross sectional view taken on the line 3-3 of Figure 2.

Figure l is a perspective detail view of one or" the longitudinal plate members employed in a stake-receiving structure of Figure 1.

Referring to the drawings, II and I2 designate respective longitudinally extending frame members of a log-carrying vehicle, forming part of the vehicle body and being rigidly secured to the body by means not shown. Secured to the ends of the respective longitudinal frame members I I and :2 are respective stake-receiving structures, each structure comprising a pair of longitudinally extending vertical plate members I3 and I4 secured to the opposite sides of the longitudinal frame member and extending a substantial dis tance beyond the end of the longitudinal frame member, to define a space between the projecting ends of the plate members I3 and I4 for receiving a vertical stake I5. The plate member It has rigidly secured thereto an eye member It and designated at I! is a transversely extending vertical plate member which is hingedly connected to the eye element I6 by means of a loop I8 integrally formed on the end of the plate member I! and engaging the eye element It, as is clearly shown in Figure 2. The plate member i I is formed with an aperture 20 through which is engageable a lug 22 formed on the end edge of the plate member I3.

.The longitudinalvertical plate member I 3 is formed with a pair oi ribs or. flanges 23, 23 to the rear portions of which'arepivotally secured the respective arms of ayoke member 2 I, as by avertical rivet 2d. Pivoted between the opposite end portions of the. flanges 23,23, as by a vertical rivet 23 a right-angled hook member 2'! whose free arm is receivable within the "yoke member 2 I, in the manner shownin Figure 2. Designated at 23 is a link bar which is pivotally connected to the end of the transverse plate member I1, as by an.

eye element 29 connected to said vertical plate member H, as shown in Figure 2. The link memher as comprises an elongated loop whose forward end portion is engageable around the shank portion of the hook element 21 in the manner shown in Figure 2, whereby the transverse plate member E i will be held in the position of Figure 2. When the yoke member 2 I is rotated clockwise, as viewed in Figure 2, to the dotted view position shown therein, the hook member 2! is released allowing said hook member to pivot counterclockwise and allowing the link member 28 to become disengaged from the hook. This releases the transverse plate member I'!, allowing the stake I5 to fall out of its pocket under the weight of the logs piled on the vehicle body, as will be subsequently explained.

The yoke member 2! is biased counterclockwise toward locking position by a coiled spring 313 connecting said yoke member to the adjacent lon-' gitudinal vertical plate member I3, as shown in Figure 3.

Designated at M is a transversely extending rod. member which is slidably mounted beneath the longitudina1 frame members II and I2, as by respective pairs of U-shaped supporting brackets 32, 32 secured to the under surfaces of the longitudinal frame members II and I2 in transverse alignment, one end of the bar 3| being formed with the eye loop 33. Each yoke member 2| is formed with the rearwardly extending arm. 34, and the arms 34 are connected by respective link bars 35 to the transversely extending, slidable bar 3|, as shown in Figure 1. It will thus be readily apparent that by moving the bar 3| to the left. as viewed in Figure 1, the respective yokes 2| will be rotated clockwise, as viewed in Figure 1, releasing the respective hooks 21, and hence releasing the respective transverse vertical plate members 11. As above explained, when the transverse plate members 11 are released, the weight of the logs on the vehicle body causes the stakes IE to fall out of their pockets and allows the logs to roll off of the vehicle body. Obviously, the release bar 3| may be actuated from a remote point, as by connecting a length of cable to the loop 33, whereby the operator may stand at a safe dis:-

tance from the vehicle and release the stakes I5 I thereof by pulling on the cable.

While a specific embodiment of an; improved stake releasing structure for log-carrying vehicles has been disclosed in the foregoing description, it will be understood that various modifications within the 's'pirit'of'the invention may occur to those skilld in the art. 1 There'- fore, it is intended that no limitations be placed on the invention [except as defined 'by'the scope of the appended claiint What is claimed is; In a vehicle of the type having spaced parallel log supporting bolsters means for releasably supporting stakes on the bolsters in vertically extending position adjacent opposite ends of said bolsters and for simultaneously releasing the stakes adjacent one side" of the vehicle and permitting them to fall away from the bolsters, said means comprising pairs of spaced parallel side plates carried by the bolsters and extend 'ing longitudinally therefrom to define with the extends across the adjacent ends of its respective pair of side plates and in closing relation to the end of the recess defined between the side plates and the bolster to an inactive position in which the end of the recess is wholly open, a lug carried by the opposite side plate and extending longitudinally therefrom adjacent the open end of the recess, the end plate having an opening extending therethrough for receiving the lug whenthe end plate is in active position, an elongated p carried by the end plate in spaced relation to the recess, a hook carried by the plate carrying the lug for movement in an arcuate path adjacent the side of said the 'plate carrying the lug for movement in an arcuate path which intersects the path of movement of the adjacent hook for holding said hook in loop retaining position, a spring carried by the bolsterand connected to the yoke for moving said yoke into hook retaining position, a lever carriedyby each yoke and projecting outwardly therefrom for moving its respective yoke in its arcuate path into hook releasing position, an operating rod mounted on the bolsters for shifting movement transversely thereof, and means carried by the rod and connected to the levers adjacent ends of the bolsters for moving the levers against the effort of the springs to release the hooks.
